Clean useless files and directories

[Peter Flanagan]

Hello,
working on Jenkins 2.150 hosted on on AWS-EC2, jenkins_home dir is located on an EFS

The space of some Jenkins instances increase dramatically due to folder not removed automatically by internal Jenkins storage management.

Using multi-branch jobs I got 2 major issues:
- some branches directories stay on file system despite the branches does not exist anymore on GUI
- some workspace__* directories stay also on FS despite the build workspace always linked to the last waorkspace (without __ suffix)

I'm wondering how to clean these two useless (according to me) directories properly.

Thanks very much for your help

You mean multi-branch "pipeline" jobs? In the job config page, Orphaned Strategy section, you check the "Discard old items" check box.
